Communication Vessel Apparatus
Product Code : SCL-PL-11818
Communication Vessel Apparatus (SKU SCL-PL-11818), also called communicating vessels, shows that a liquid poured into connected tubes settles at the same level in each one, whatever the size or shape of the tube. It suits liquid-pressure lessons from middle school to Class 11 physics. Science Lab Supplies manufactures the apparatus in its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, for schools, colleges, tender contractors and distributors buying direct.
Specifications
Four vertical glass tubes, each of a different shape and size, rise from one common horizontal pipe so that liquid can flow freely between them. The assembly is mounted on a 230 x 100 x 22 mm wooden base and stands 160 mm high overall.

Applications and Experiments for the Communication Vessel Apparatus
The apparatus demonstrates that the pressure in a liquid at rest depends only on depth, so connected columns reach one common height regardless of shape or width. It supports liquid-pressure topics from CBSE/NCERT Class 8 science to Class 11 physics, and it belongs on any list of school physics lab equipment in India.
- Class 8 science (Force and Pressure): liquids exert pressure and find their own level.
- Class 11 physics (Mechanical Properties of Fluids): hydrostatic pressure depends on depth, not on vessel shape.
- Discussing everyday examples such as water tanks feeding taps and a teapot and its spout.
Standard Scope of Supply
The Communication Vessel Apparatus is supplied as a single unit: the four glass tubes on their common horizontal pipe, mounted on the wooden base. Water and any colouring used to make the levels easier to see are provided by the laboratory; optional accessories are listed on the quotation.
Packing, MOQ and Lead Time
Ask for one unit for classroom demonstration or a set for each practical group. Science Lab Supplies replies with a quotation that gives the packing, delivery time and price for the quantity requested, and other fluid-pressure apparatus can be included on it.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and is able to ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines.

Frequently Asked Questions
What does the Communication Vessel Apparatus demonstrate?
It shows that liquid in connected vessels settles at the same height in every tube, even when the tubes differ in shape and size, because pressure in a still liquid depends only on depth.
How big is the apparatus?
It stands 160 mm high on a wooden base measuring 230 x 100 x 22 mm, which makes it easy to place on a demonstration desk or a student bench.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this apparatus itself. It is produced in Saha, Ambala, India, and you deal with the manufacturer directly for the quotation and supply.
Why might the level in a very narrow tube look different?
In very narrow bores, capillary action can raise or lower the surface slightly. Read the levels at the flat part of each surface and compare the wider tubes for the clearest result.
